LVCMOS, LVTTL, HSTL 15 D0 LVPECL, CML, LVDS, Inverted differential clock/data D0 input (Note 1). LVCMOS, LVTTL, HSTL 16 VTD0 Internal 50 termination pin for D0. EP Exposed pad. EP on the package bottom is thermally connected to the die improved heat transfer out of package. The pad is not electrically connected to the die, but is recommended to be soldered to GND on the PCB. 1. In the differential configuration when the input termination pins(VTD0/VTD0, VTD1/ VTD1) are connected to a common termination voltage or left open, and if no signal is applied on D0/D0, D1/D1 input, then the device will be susceptible to selfoscillation.
